RFC 3496    ATM Service Class-aware MPLS Traffic Engineering  March 2003

1. Overview

   This document defines a Resource ReSerVation Protocol-Traffic

   Engineering (RSVP-TE) protocol addition to support ATM (Asynchronous

   Transfer Mode) Service Class-aware MPLS (MultiProtocol Label

   Switching) Traffic Engineering.

   This protocol addition is used with all MPLS Label Switched Routers

   (LSRs) and link types (including, but not restricted to, Packet over

   SONET, Ethernet, and ATM links) to signal traffic engineered paths

   that can support the ATM service classes as defined by the ATM Forum

   [TM].  This document does not specify HOW to actually implement the

   functionality in the MPLS LSRs to emulate the ATM Forum service

   classes (such as necessary queuing and scheduling mechanisms), only

   how to signal that the TE path must support t...
